Benefits of technology

[0008]An aspect of some embodiments of the invention provides apparatus and methods for dispensing, via an outlet of a container holding a fluid, a plurality of controlled doses of the fluid by a plurality of tubes which selectively connect and disconnect chambers within the container according to the position of the tubes in the dispenser. The selective connections effect loading the chambers with the fluid and a subsequent discharge thereof.

Problems solved by technology

Often, after dispensing a fluid, some fluid residues remain in the nozzle and may dry out or otherwise change, resulting in clogging or obstructing the passage of fluid in and out of the nozzle.

Abstract

A method for dispensing a plurality of metered doses of a fluid, comprising: providing a fluid in a container comprising a plurality of metering chambers and a plurality of tubes connectable to and movable relative to the chambers, wherein the tubes are externally open or open to the fluid; connecting to the chambers tubes open to the fluid, thereby loading the chambers with fluid; and selectively connecting one or more externally open tubes to one or more chambers, thereby dispensing the fluid contents of the one or more chambers via an external opening.

Description

FIELD OF THE INVENTION[0001]The invention generally relates to fluid dispensers. Some embodiments of the invention relate to apparatus and methods for dispensing preset quantities, wherein some embodiments further relate to self-cleaning dispensers.BACKGROUND OF THE INVENTION[0002]Fluid dispensers are commonly found in household or engineering applications such as perfume bottles, cosmetic foams, pharmaceuticals, disinfectant or oil or paint dispensers or others such as aerosol canisters.[0003]Typically a fluid in a container is pushed out due to a pressurized propellant such as a gas pre-filled or pumped into the container, or the fluid is drawn out by a pump or a squeeze.[0004]In some ordinary cases the dispensers have a continuous operation, that is, as long as a release valve is activated the fluid is expelled. In other cases the dispensers operation is intermittent, that is, some volume is delivered in a manner responsive to pumping or squeezing.[0005]In some applications, for ...
